create PUT request: %w

Error message

create PUT request: %w

What it means

HTTP client error in MinerUCloudReader.uploadFile: http.NewRequestWithContext could not construct the PUT request for the presigned upload URL. The %w retains the net/http cause; it fires before any bytes are sent to object storage.
